General Health Information

Perhaps the biggest complaint about these over the counter dental bleaching products
is that they do tend to cause irritation to the gums when the gel leaks
out from behind the tray. This problem is caused mainly by the user
when they use too much of the teeth bleaching gel. However, by limiting
use and making sure to trim the tray before using (remember, these are
one-size-fits-all trays so they are typically larger than they need to
be).
